后端json对象的使用和特性

后端也可以做json对象的存储，具体的使用实例如下：

1、数据模版

{
    "contractId": 2611141940251005036,
    "documentParams": [
        {
            "name": "乙方姓名2",
            "value": "邓茜茜"
        },
        {
            "name": "乙方姓名3",
            "value": "邓茜"
        }
    ]
}

2.1、具体使用——list

public Result<String> fillParams(@RequestBody JSONObject object){
        Result<String> result = new Result<>();
        String contractId = object.getString("contractId");
        String bizId = object.getString("bizId");
　　　　　//获取数据对象
        JSONArray documentParams = object.getJSONArray("documentParams");
        List<DocumentParamDto> documentParamDtos = documentParams.toJavaList(DocumentParamDto.class);
    try {
　　　　　//处理数据变量
        result = contractLockService.fillParams(Long.valueOf(contractId),bizId,documentParamDtos);
    }catch (Exception e) {
        e.printStackTrace();
        result.error500(e.getMessage());
    }
    return result;
}

2,.2、具体使用——map

  public Result<String> fillParams(@RequestBody Map<String,Object> map){
        Result<String> result = new Result<>();
        String contractId = map.get("contractId").toString();
        Object documentParams = map.get("documentParams");
        List<DocumentParamDto> documentParamDtos = JSON.parseArray(JSON.toJSONString(documentParams), DocumentParamDto.class);

        return result;
    }

2.3、hutool使用json

JSONObject object = JSONObject.parseObject(execute);
        String result1 = object.getString("result");

        if (ResponseCodeEnum.SUCCESS.getCode()
                .equals(Integer.parseInt(object.getString("code")))){
            result.setCode(200);
            JSONArray jsonArray = JSONUtil.parseArray(result1);
            result.setResult(JSONUtil.toList(jsonArray, TemplateEntity.class));
            result.setMessage(object.getString("message"));
            return result;
        }
